MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 760,509, dated May 24:,1904.

Application filed January 81, 1901. Renewed March 22, 1904. Serial No.199A31. (No model.)

1'0 all whom it pea/y concern.-

Be it known that I, EDGAR A. WRIGHT, a citi- Zen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Motor-Vehicles, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

Figure 1 is a plan view with the deck removed. Fig. 2 is a sectionalside elevation. Fig. 3 is a transverse section on the line 00 w ofFig- 1. Fig. 4 is an enlarged transverse section on the line y y of Fig.2. Fig. 5 is an enlarged detail in section of the engines in sectionthrough the cylinders.

In this apparatus is comprised a platform A, supported upon atruck-frame B, as by springs C C, the truckframe having rear axle I),forward. axle D, rear carrying-wheels E, and forward carrying-wheels E.The rear carrying-wheels are provided with chainwheels F F, connected bychains F F to chain-wheels G G on the outer ends of a twopartcounter-shaft G G", journaled transversely of the truck-frame and unitedat the inner ends by a compensating gear, (represented. as a whole atH.) The central member of the compensating gear H is in the form of achain-wheel it, so that power applied thereto will be communicatedequally to the carrying-wheels E through the chain-wheels and chainsabove noted.

The forward carrying-wheels E are provided with bevel-gears I I, adaptedto be actuated through trains of bevel-gears I I from a transversetwo-part counter-shaft J J, the latter journaled upon the truck-frameand united at the inner ends by a compensating gear, (represented as awhole at K.) The central member of" the compensating gear is in the formof a chain-wheel 12, so that power applied thereto will be communicatedequally to the carrying-wheels E through the bevelgears above noted.

The forward axle D is formed in three partscentral part (Z and end parts(1 d, the end parts carrying the wheels E and united to the ends of thecentral part by vertical pins, (indicated by dotted lines at a? (Z2) andthe bevel-gearing is so arranged and connected that the wheels E may beturned, as by the levers L, to guide the vehicle without affecting thecounter-shaft J J or the compensating gear K carried thereby.

Supported by the platform-framework A are two or more engines, allarranged to be supplied with steam or other power by one supply-pipe Mcommon to all the engines and provided with a throttle-valve, (indicatedat M.) In the drawings four engines are shown, (indicated at N N N N,)the engines N N coupled to actuate one common shaft P and the engines NN" coupled to actuate one com mon shaft P. This is the preferablearrangement; but one or more engines may be arranged to actuate each ofthe shafts P P, if circumstances require it. The shafts P P are suppliedwith cl1ainwheels P P", connected, respectively, by chains P P to thecentral chain-wheel members h it of the compensating gears H K, asshown.

The supply-pipe M branches, as at m m m m, to the four valve-chambers aa n a of the four engines N N N N, as shown, so that the steam or otherpower employed will flow equally to all theengines at all times and afree communication maintained continuously between all the engines andthe common supply-pipe, so that the pressure is equalized in alltheengines. The strains throughout the whole vehicle are thereby perfectlyequalized, and any inequality of strain or pressure will be at onceabsorbed by the connected mechanism and distributed equally throughoutall the parts, and by arranging the compensating gearing between theengines and the carrying-wheels any inequality of strains exerted uponthe wheels will be likewise equalized and distributed. The wholeapparatus is thus rendered automatically adaptable to the varyingconditions of the road-bed and strains effectually prevented from beingunequally exerted on any part of the machine.

The boiler may be of any improved construction and may belocated at anyconvenient point on the bed-frame Aas, for instance, atone of theforward corners, as indicated by dotted lines at R.

The power employed will generally be steam; but compressed air or othersimilar power may be employed.

What I claim is 1. In a motor-vehicle the combination of fronttraction-wheels, rear traction-wheels, an actuating mechanism for saidfront wheels, an actuating mechanism for said rear wheels independent ofthat for said front wheels, a pair of connected engines connected whollywith one of said actuating mechanisms, a second pair of connectedengines connected Wholly with the other of said actuating mechanisms andindependent of said first pair, and a common source of fluid-pressurefor said engines.

2. The combination of front and rear traction -wheels, a pair ofconnected engines, means for applying equal independent drivingpressures from said pair of engines to said front wheels individually, asecond pair of connected engines independent of said first pair, meansfor applying equal independent driving pressures from said second pairof engines to said rear wheels individually, and a common source offluid-pressure for all of said engines.

3. The combination of the main frame having traction-wheels at one endand traction and steering wheels at the other end, a pair of enginesconnected with the traction-wheels to drive the same, a pair of enginesindependent of the first pair and connected with said traction andsteering wheels to drive the latter independently of the former wheels,and means for supplying a common driving pressure to said engines.

4:. The combination of the main frame having traction-wheels at one endand traction and steering wheels at. the other end, apair of enginesconnected with the traction-wheels to drive the same,'a pair of enginesindependent of the first pair and connected with said traction andsteering wheels to drive the latter independently of the former wheels,and means for supplying a common driving pressure to said engines, saidengines being arranged centrally of and beneath the main frame betweenthe front and rear wheels.

5. The combination of the main frame, traction-wheels at one endthereof, traction and steering wheels at the other end thereof, anengine, longitudinal chain and compensating gear driving saidtraction-wheels from said engine, a second engine independent of thefirst having a longitudinal chain and compensating gear connecting thesecond engine with the traction and steering wheels and independent ofthe driving mechanism of the first engine, and means for supplying acommon driving pressure to said engines.

6. The combination of the main frame, traction-wheels at one end.thereof, traction and steering wheels at the other end thereof, a pairof engines, alongitudinal chain running from a point between saidengines, a compensating gear connected with said tractionwheels and withsaid chain, a second pair of engines independent of the first pair, alongitudinal chain running from a point between said second engines, acompensating gear connected with the driving and traction wheels andwith the latter chain, and means for supplying a common driving pressureto said engines.

7. In a motor-vehicle, two or more engines having one common supply-pipewhereby power is supplied equally to all of said engines, the forwarddriving-gear, the rear driving-gear, means for independently connectingone or more of said engines to said forward gear, and means forindependently connecting one of said engines to said rear gear, andcompensating gearing between said engines and said front and rear gearswhereby all strains are equalized and uniformly distributed,substantially as set forth.

8. In a motor-vehicle, two or more engines having one common supply-pipeand one common throttle-valve, whereby power is supplied equally to allthe engines, a forward axle having independent carrying-wheels, a rearaxle having independent carrying-wheels, means for independentlyconnecting one or more of said engines to actuate said forwardcarryingwheels, and means for independently connecting one or more ofsaid engines to actuate said rear carrying-wheels, substantially as setforth.
